SPECIFICATION forming part of Letters Patent No. 395,789, dated January 8, 188.9.

Application filed December 19, 1887. Serial No. 258,353. (No model.)

To all whom it may concern:

Be it known that I, EDWIN .l'oHNsoN LUM- LEY, a subject of the Queen of Great Britain, residing at \Vashington, :in the District of Columbia, have invented certain new and usefnl Improvements in Machines :for Making Ci garcttes; and I do declare the following to be a full, clear, and exact description oi' the in vention, such as will enable others skilled in the art to which it appcrtains to malto and use the saine, reference being had to the accompan ying drawings, and to the letters and iigures of reference marked thereon, which form a part ot' this specification.

My invention relates to certain novel. improvements in machines for making cigarettes, which improvements will be fully un derstood from the following description, taken in connection with the annexed drawings, in whichw Figure l is a plan view of a cigarettemachine embodying my improvements. Fig. 2 is a broken view, in elevation, of the front side of the same. Fig. 3 is a vert-ical longitudinal sectional view taken in the course of the dotted line fg on Fig. l. cross-sectional view showin the thread-guide and pressure pasting-roller, the section being taken on line t +L, Fig. 3. Fig. 5 is an en larged detail view, in perspective, of the pastereceptacle, the thread-guide, the thread-carry ing devices, the forming-tube and trough, and the spring-actuated pressure or pasting roller. Fig. G is a reduced vertical sectional view through the paste-receptacle, showing the tube through which the thread 4passes in longitudinal section. Fig. 7 is a side elevation of the trimming mechanism. Fig. S is a face view of the trimming mechanism, parts of which are shown iu dotted lines. Fig. 9 is a detail view, in perspective, of the double-.cam wheel,

the pasting-roller with its eccentric boss, the

Fig. 4.- is a detaill ner side view ot' the double cam detached from the pulley. Fig. 13 is a transverse sec tion through the grooved pulley, taken in the plane indicated by dotted line a: ce on Fig. ll, the double cam being removed. Fig. I4. is a vertical transverse section through the hopper, taken in the plane indicated by dotted line h 7i. on Fig. Fig. l5 is an enlarged horizontal sectional View in detail of the paste-receptacle c, showing the peculiar arrangement of the endless thread n., the tube d, and the rolling-guides tor said thread. Fig. it is an isometrical view ot the feed-bar J detached from the machine.

Referring by letters to the annexed drawings, A designates the table or stand upon which the working parts of the machine are erected.

B is the main shaft, which is mounted in bearings below the table, and is operated by a treadle, C, or by other suitable motive power.

D is the feedhopper, which is supported upon suitable legs above the table A, and is provided on its interior near one end with a swinging apron, E, which tapers laterally from above downward, as clearly shown in the sectional view, Fig. 14, and is supported by projecting arms F F at its upper corners in vertical slots G in the side walls of the hopper D.

It will be observed that the arms F F afford pivotal guides for the upper broad end of the apron E, and that the lower contracted end of this apron is loosely iitted into a transverse notch, j X, formed in the rectangular portion of the reciprocating bar J.

The apron E is provided with a downwardly and forwardly curved agitating-arm, I-I, which is rigidly secured to said apron, and which terminates at the lower end in abachwardlydirected portion, hx. A spring, I, is secured to the edge of the hopper at one end, and is extended downward and forward and bears upon the arm H, as shown in Fig. 3.

The feed-bar J is a rectilinear reciprocating bar, and is toothed at J for a portionof its length. It will be observed by reference to Soi Figs. 3 and 1G that the forward toothed portion of the bar J presents a series of pairs of forwardly-directed teeth, ji", which at each forward stroke of the bar J will feed the loose cigarette material into a tube, R, but which during the return-stroke will shed the filling,

leavin the same in said tube. The said feedbar provided on its upper side at its outer end with astud, K, which entersaeam-groove,

1o L, in the drum M. On. the inner end oli' the drum M is a pulley, N, over which a belt, l),

is run from the driving-pulley Q on the main shaft 1).

A tapered :forming-tube, R, is secured in the bottom of the feed-hopper D and extends back a short distance therein, terminating in.

a flaring inner end, and this tube projects forward and just enters the rear end ol' the pasting-trough S. This tube ortobacco-conductor R 2o has an internal passage or bore, which diverges from the hopper D to a thin delivering end, fr', which externally is of less diameter than the entering end of the trough S, leaving an annular spaceyr?, as clearly shown in. Fig.

The pasting-trough S is supported by an angular bridge, T, the rear arm of which is secured to the forming-tube R. At the front end of the bridge T is secured a bifurcated spring-arm, U, and in the free end of this arm 3o is journaled Athe iianged pressure or pasting roller W, beneath which the formed cigarette is passed by the pressure exerted on the material behind it.

X is the spool upon which the continuous 3 5 cigarette wrapper 'Y of cigarette -paper is wound, said spool being preferably supported at the left-hand end ol' the table, as shown in Figs. 1 and 2. The cigarette-wiappe r 'Y passes beneath hopper D and through the trough S,

4o entering the annular space r2 in the manner shown in Fig. 5, at and near which point or space the said wrapper is formed .into a tube and the longitudinal edges thereof lapped, as shown in Fig. et; but previous to the closing of the wrapper a suitable paste or cement is h placed between them, as will be hereinafter explained.

The pastingtrough S is open at both ends, and is also open at its upper side between the 5o cylindrical portions a b, in which opening' the pasting..pressure-roller lV operates toip'ress the lap of the wrapper. The paste-holder c is located at one side of the pasting-trough S, and is provided with a projecting horizon- 5 5 tal tube, CZ, through which an endless thread, n, passes while being coated with paste. The discharge end or nipple (ZX of this tube (l is directed toward the discharge end of the trough S and flattened horizontally7 so thatit 6o affords a narrow feed for introducing paste between the longitudinall lapping edges of the wrapper Y before the roller W` operates to press the lapped edges together.

On one side of the paste-holder c is secured a standard, e, which is adjustable and can be held in place by means of a tlnnnb-screw, f,

passed through a slot, g, in the foot of said l standard, for the purpose of keeping' the endless paste-feeding thread under proper tension. The upper arm, 71 of the standard c is bifurcated to receive a grooved disk, t, which is journaled vin said arln so as to rotate in a horizontal plane.

T o the tube (l is suitably secured an arm, Z, which is provided with a small pulley, fm, journaled in a bifurcation in this arm. The pasting-thread n passes horizontally through the paste-holder, through the tube d, and around the pulley m and disk i. This thread n is a continuous paste-feeder for evenly distribnting a sufficient quantity of paste between the lapping edges of the cigarettewrapper Y on its way through the trough S. The periphery of roller 1V impinges upon the lapped edges of the wrapper Y between the said nipple (ZX and pulley m with ayielding pressure, exerted by spring U, which pressure is sufficient to seal the pasted edges of the wrapper.

It will be observed that arm lis adjustable. This adjustment is designed for giving a proper pressure of the roller m upon the thread, whereby the tension o f the endless thread and its direction can be regulated. This adjustment is made by means of a screw, 7L. This operation forms a continuous roll of tobacco covered by a tubular wrapper, and the operation of the feeder .l and thread a should be synchronous.

1 is a standard secured upon the table A, near the right-hand end of the same. ln its upper end this standard is provided with a short shaft, 2, from which is hung the depending parallel arms 3 and l, and between the upper ends ol' the arms 3 4. lis journaled the double pulley 5 (5. The arms 3 and are secured tothe opposite sides of a block, 7, which separates them.

In the lower ends of the swinging arms 3 al is journaled a short shaft, 8, which is provided with a fast pulley, 9, and a balancewheel, 10. A belt, 11, runs from the pulley 5 to the pulley 9. The double pulley 5 (i is driven from a wheel, 12, on the shaft B. On

the outer end of the shaft 8 is secured a triimLl'iing-knife, 141, held removably in place by a nut and washer.

On one side of the block 7 is secured a spring catch-carrier arm, ehwhich is provided at its lower curved end with a shouldered inclined portion, 15, which is designed to engage the spring-arm ,16. vided with a beveled dog, 17, which bears against a double cam, 1S, on wheel 20. A spring-arm, 19, is secured to the standard 1, which arm bears against the face of the block 7 and keeps the knife 14 free from the cigarette, or in the position shown by Fig. 8 in full lines,

except during the act of cutting off a length4 thereof, when the parts are in the positions indicated in dotted lines, Fig. 8. Theswinging knife-carrier is moved to the position indicatedin full lines, Fig. S, by the pressure of the spring 19, and it is moved in theoppo- This arin 16 is pro-' IOO site direction, or to the position shown by dotted lines in Fig. 8,by the combined action ot a double cam, 18, on the wheel 20, the dog 17, the spring-arm 16, the catclrcarrie'r arm 44, and a push-pawl, 32, which forces the cam to pass the dog. The shaft 21 is supported in a journal-box, 22, (shown in Fig. 1,) and on this shaft is applied a grooved oscillating pulley, 23, in front oll which is applied on the same shat't a double-'face cam-wheel, 20.

In front ot' the grooved pulley 23 a recess, 2l, (see Fig, 13,) is provided, and also a small recess, 25, which latter is designed to receive a spiral spring, 26, that bears against the inner :face of a short plate, 27, loosely attached near one end by a screw, 23, which plate :forms a clutch to engage the pins 2f) and 30, protruding from the side ot the wheel 20, so that when the grooved pulleyis rocked acon tinuous intermittent rotary movement in one direction is imparted to the double wheel 20, which imparts motion te the springarm 16 by the double cam 1S,which it carries, en gaging the dog 17 and causing said spring-arm 16 to operate the catch-carrier arm 4.1-, and thus by engaging its shoulder 15 and moving it to the let't causes it to swing the knife-carrying arms into position to permit the knife to cut ott' a cigarette :from the long tube ot' wrapped tobacco. As the stock is Al'ed it'orward, the next cut ot the knife severs from said tube another cigarette, and so on.

VUpon the upper end of a short vertical standard, 31, is pivoted a lever, 32, which is engaged by a vertical spring, 33, extending' upward from the base-plate of said standard and serving to return said lever to its normal position after it is engaged by the cam 50011 the face of the pressure or pasting roller lV. At its outer end the said lever 32 is provided with a pivoted feed-pawl, 32, the angular point 34 ot which lies in a groove, 35, in the periphery ot' the wheel 20, and engages alternately in dianietrieally-arranged holes 36, leading from the groove 35, and serves to push the highest points of the double cam 1S past the inclined end of dog 17, as the cord 37 and wheel 23 do not turn them suiiiiciently far to pass the dog 17.

The pulley 23 is connected by a convolute spring, 3G, to shaft 21, so that this pulley may be rocked about its axis, a cord, 37, conneeting it with the treadle C, and said convolute spring 3G connecting it to the shaft 21 at its inner end by a screw, 3S. The outer end ofthe spring is secured to one side of the pulley by a screw, 40, so that when t-he said pulley has been rocked in one direction a given distance by the treadle the spring 3G will, by recoil, return it toits normal position as the pressure is removed from the treadle.
